Foldable boat ladder alarm
A boat ladder alarm system for a foldable boat ladder having a base rail and a movable rail is disclosed. In one embodiment, the boat ladder alarm system includes a first bracket, a second bracket, and a sensor system. The sensor system is configured to trigger an alarm when the first bracket and the second bracket are unconnected and to turn off the alarm when the first bracket and the second bracket are connected. In this manner, if the foldable boat ladder is unfolded and someone is trying to climb on the boat, the alarm is triggered to warn the boat operator that it is not safe to turn on the boat engine.

8. The boat ladder alarm system of claim 7 , wherein the sensor system further comprises a magnet that is provided in the second bracket so as to face the sensor when the foldable boat ladder is folded so that the alarm is turned off and is configured so that the magnet does not face the sensor and so that the alarm is turned on when the foldable boat ladder is unfolded.
9. The boat ladder alarm system of claim 8 , wherein the second bracket comprises an open loop and a back section, wherein the open loop defines an opening for receiving the movable rail and the back section attaches to the open loop so as to close the opening.
10. The boat ladder alarm system of claim 9 , wherein the magnet is received in the back section.
11. A boat ladder alarm system for a foldable boat ladder having a base rail and a movable rail of a boat, comprising:
a first bracket configured to connect to both the base rail and the movable rail of the foldable boat ladder when the foldable boat ladder is folded and to connect to the base rail and disconnect from the movable rail when the foldable boat ladder is unfolded;
a second bracket configured to connect to the movable rail and the first bracket when the foldable boat ladder is folded and to connect to the movable rail and disconnect from the first bracket when the foldable boat ladder is unfolded;
a sensor system configured to prevent the boat from starting when the first bracket and the second bracket are unconnected and to allow the boat to start when the first bracket and the second bracket are connected.
12. The boat ladder alarm system of claim 11 , wherein the first bracket comprises:
a first grip configured to receive the base rail; and
a second grip configured to receive the moving rail when the foldable boat ladder is folded and to release the moving rail when the foldable boat ladder is unfolded.
13. The boat ladder alarm system of claim 12 , wherein the first grip and the second grip are attached.
14. The boat ladder alarm system of claim 12 , wherein the first grip comprises an open loop that defines an opening for receiving the base rail.
15. The boat ladder alarm system of claim 14 , wherein the first grip further comprises a back section that attaches to the open loop around the base rail.
16. The boat ladder alarm system of claim 12 , wherein the second grip comprises an open loop that defines an opening for receiving the movable rail when the foldable boat ladder is folded and for releasing the movable rail when the foldable boat ladder is unfolded.
17. The boat ladder alarm system of claim 12 , wherein the first grip and the second grip connect at an intersection and the sensor system comprises a sensor, wherein the boat ladder alarm system further comprises a section that extends vertically downward from the intersection and defines a sensor aperture for receiving the sensor.
18. The boat ladder alarm system of claim 17 , wherein the sensor system further comprises a magnet that is provided in the second bracket so as to face the sensor when the foldable boat ladder is folded so that boat is allowed to start and is configured so that the magnet does not face the sensor and so that the boat is prevented from starting when the foldable boat ladder is unfolded.
19. The boat ladder alarm system of claim 18 , wherein the second bracket comprises an open loop and a back section, wherein the open loop defines an opening for receiving the movable rail and the back section attaches to the open loop so as to close the opening.
